WRENCH.

Specification for Design.

Patented Mar. 22, 1921.

Application filed AugustfZ, 1920. Serial No. 400,771.

To all to 710m it" may concern Be it known that may, a citizen of 1, \VILLIAM TANKERS- the United States, residing at Denver, in the county of Denver and State Colorado, useful Improvements the following is a spe have invented certain new and in renches of which cihcation, reference being had to the accompanying drawings.

This invention relates to certain improvements in wrenches, and it is primarily an object of the invention to provide a novel and improved device of this general character whichis an imp of wrench disclosed 1 rovement over the type n my prior Patent ho.

1,293,243, dated February 1, 1919.

it is also an object of the invention to provide a novel and improved device of this general characte including a ing of a plurality of shank consistsections connected for relative angular adjustment, together with means for positively locking said sections in their various arrangements.

The invention consists in the details of dered simpler, more convenient and as will be hereinafter less expensive and otherwise advantageous for use, more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my bette understood, 1

invention may be the will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 1s a side elevation of my improved wrench,

Fig. 2 is a longitudinal sectional view of a portion thereof, and

Fig. 8 is an edge or plan view or the de vice.

As disclosed ings, S denotes the wrench which consist in the accompanying draw shank of my improved s of two sections 1 and 2. The inner end of the section 1 is pro vided with a pair of transversely spaced wings or leaves 3 which extend beyond a face of the section 1 and which are substantially circular in contour and of equal radii.

Snugly fitting between the wings or leaves 3 is a substantially circular head i carried by the inner end of posed or leaves by the sections 1 an the section 2 and disthrough the axial center of the wings 3 and the head 4: is the pin 5 whered 2 are pivotally connected so that said sections may be angularly adpisted one relative to the other. The periphery of the head 1 terminates a material distance inwardly of the periphery of the wings or leaves 3 so that in practice the peripheral portion of the head 1 will be protected and more particularly the outer or entrance ends of the recesses 6 produced in the periphery of said head.

The inner end of the section 2 at opposite sides of the head 4 is provided with the inwardly directed ribs 7 which overlie the marginal portions of the wings or leaves whereby said wings or leaves are materially reinforced during a working operation.

The section 1 at substantially its axial center is provided with a longitudinally disend of said spring bearing against the inner or closed end of the bore 8 wnereby the shank 9 is constantly urged outwardly.

The outer end of the shank 9 is provided with a laterally extending lug 1 1 terminat ing in a forwardly directed tongue 15, said tongue 15 being adapted to engage within a recess 6 so that the sections 1 and 2 may be effectively locked in alinement or at different relative angles as occasioned by the requirements of practice and as permitted by the recesses 6. As is clearly illustrated in Fig. 2 of the accompanying drawings, the lug 1 1i is of a length whereby the tongue 15 is positioned radially of the connecting pin 5.

A face of the section 1, or the outer face thereof when the sections 1 and 2 are in folded relation, is provided with a longitudinally directed slot 16 in communication with the bore 8. Disposed through the slot 16 is a shank 17 in threaded engagement or otherwise secured to the shank 9 and at such a point on said shank 9 whereby the contact of the shank 17 with the inner end of the slot 16 limits the inward movement of the shank 9 with the outer face of the lug 1d substantially flush with the inner end of the section 1 and at which time the tongue 15 seats within a recess 6. The slot 16 is of a length to permit the requisite endwise movement of the shank 9 to withdraw the tongue 15 from within a recess 6 when the shank 17 isat the limit of its outward movement and as controlled by the outer end of the slot 16.,

The outer end of the shank 17 is integrally connected with a head 18 herein disclosed as hexagonal in form and having its outer The desired relative movement of the aws a and Z) is obtained in the same manner as set forth in-my prior Patent N 0. 1,293,243, h'ereinbefore referred to;

The outer end of the section 2 is also of a construction and form as is particularly illustrated in my prior patent just referred to and which includes the relatively movable jaws 0 and d and an opening 19 with which is adapted to be engaged a suitable handle or lever for imparting the requisite turning or swinging movement to the shank S'when the occasions of practice may so require.

From the foregoing description it is thought to be obvious that a wrench constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with signature.

which it may be assembled and operated, andit will also be obvious that my invention is susceptible ofsome change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the severalparts herein shown in carrying out my invention in practice except as hereinafter claimed. 7

I I claim:

A wrench comprising, in combination, a shank consistingflof two sections, a hinge joint therebetween to fold the sections one upon the other or at intermediate angles, one of the hinge joint members having a series of recesses, the adjacent end portion of the second section being providedwith a longitudinally disposed bore, a shank slidably mounted in said bore, means for constantly urging said shank toward the hinge joint, the, outer end of the shank being provided'with a laterally extending lug terminating in a forwardly directed tongue adapted to engage within a'recess carrled by one of the hinge joint members, said tongue being disposed radially of the hinge joint, said second section of the shank be ing provided with a longitudinally disposed slot in'communication with a bore therein, a shank disposed through said slot and secured to the shank, said second named shank constituting an operating member, and a head carried by the outer end of said second named shank and adapted to be engaged by the digit of a hand.

In testimony whereof I hereunto affix my WILLIAM TANKERSLEY.
